Copy link

Red Hat Connectivity Link is a modular and flexible solution for application connectivity, policy management, and API management in multicloud and hybrid cloud environments. You can use Connectivity Link to secure, protect, connect, and observe your APIs, applications, and infrastructure.

Connectivity Link is based on the Kuadrant community project. Connectivity Link provides a control plane for configuring and deploying ingress gateways and policies based on the Kubernetes Gateway API standard. Connectivity Link supports OpenShift Service Mesh 3.0 as the Gateway API provider, which is based on the Istio community project.

See the Red Hat Connectivity LInk Life Cycle Policy for details about version support and OpenShift Container Platform compatibility.

Copy link

Developer Preview features are included in Connectivity Link 1.1.

Important

Developer Preview features are not supported by Red Hat in any way and are not functionally complete or production-ready. Do not use Developer Preview features for production or business-critical workloads. Developer Preview features give you early access to functionality in advance of possible inclusion in a Red Hat product offering. Customers can use these features to test functionality and give feedback during the development process.

Developer Preview features might not have any documentation, are subject to change or removal at any time, and have received limited testing. Red Hat might provide ways to submit feedback on Developer Preview features without an associated SLA. For more information, see Red Hat Developer Preview - Scope of Support.

Red Hat customers can give feedback on Developer Preview features through your account teams. You can also ask questions and give feedback directly by using the Connectivity Link contact form or by emailing rhcl-contactus@redhat.com.

1.5. Fixed issues
Copy link

See the included list for bugs that are fixed in Connectivity Link 1.1.

1.5.1. Fixed issues in Connectivity Link 1.1.1
Copy link

  • Previously, for RateLimitPolicy or AuthPolicy only, you were required to authenticate to registry.redhat.io to access the WASM plugin image used with OpenShift Service Mesh as the Gateway API provider. Authenticating to registry.redhat.io to access the WASM plugin image is no longer required. (CONNLINK-529)
  • Previously, on OpenShift Container Platform 4.19, Connectivity Link used an incorrect Gateway API controller name. The Gateway API controller name is required to enable the Gateway API Custom Resource Definitions (CRDs). Now, Connectivity Link uses the correct Gateway API controller name for OpenShift Container Platform 4.19. (CONNLINK-433)

1.5.2. Fixed issues in Connectivity Link 1.1.0
Copy link

  • Previously, in the Policies view, in a specific policy list such as DNS policies, when you switched namespace, you returned to the All Policies view. Now, when you switch namespace, you stay in the original specific policy list. (CONNLINK-289)

1.6. Known issues
Copy link

Listed are the known issues that apply in Connectivity Link 1.1.

  • Connectivity Link allows configuration for non-standard response codes. Connectivity Link should not allow configuration that specifies non-standard custom HTTP response codes such as HTTP 333 (CONNLINK-287).
